Air Traffic Control (ATC) refers to the system and personnel responsible for managing and directing aircraft both in the sky and on the ground. ATC ensures the safe, orderly, and efficient movement of air traffic, preventing collisions and coordinating aircraft takeoffs, landings, and routes. In cybersecurity, ATC systems are critical infrastructure, often targeted by cybercriminals due to their importance in national security and public safety. Securing ATC networks and communications is essential to prevent disruptions, unauthorized access, or manipulation that could endanger lives and disrupt air travel.
